Behaviour

Eighty fills is not a sin. Eight chaotic ones might be.

Fill count means nothing without the plan it is compared against — and without the charges it generated.

Overtrading is the most casually diagnosed condition in retail trading, usually by people counting somebody else’s fills.

Eighty trades on an expiry day may be a scalping process executed exactly as intended. Eight trades on a random Wednesday may be pure drift.

Compare count to your own plan

The morning card can hold an expected activity level. Then the question becomes answerable: did the session match the intent, or did it triple it?

Fill count versus net P&L, one year of sessions

High-count sessions were not automatically bad, but the worst days all sat on the right. Illustrative journal data, not a live book and not a performance claim.

Quality has to be tagged in the moment

Marking every green trade as a good setup after the fact is how a journal becomes a scrapbook. If quality is going to be a field, it has to be filled before the outcome is known.

Put the charges next to the count

On a flat day, transaction costs from extra fills can be the entire result. That single comparison — charges as a share of gross — tends to end the overtrading debate faster than any lecture.

The comparison that ends the argument
₹4,100 Gross P&L on a 40-fill day looked like a green session
₹4,021 Total charges that day brokerage, STT, exchange, stamp, GST
₹79 What actually landed Illustrative, but not unusual
